White93z34 Posted December 29, 2006 Report Posted December 29, 2006 I'd say that is the flex fuel 3.1 myself. simply because their isn't anything else to choose from. Quote
Euro Posted December 29, 2006 Report Posted December 29, 2006 i didnt know there was a flex-fuel 3.1. Where was these available? Quote

chadz34 Posted December 29, 2006 Report Posted December 29, 2006 So, what is flex fuel? What makes this engine so different from other 3.1's? Quote
digitaloutsider Posted December 29, 2006 Report Posted December 29, 2006 It can run gasoline with higher levels of ethanol. It also had "VARIABLE FUEL" stamped in the plenum. Quote
chadz34 Posted December 29, 2006 Report Posted December 29, 2006 It can run gasoline with higher levels of ethanol. It also had "VARIABLE FUEL" stamped in the plenum. That's weird...were there other cars that had this or was this kindof a step by GM thinking higher levels of ethanol would be put into fuel in the future or what? Quote
Euro Posted December 29, 2006 Report Posted December 29, 2006 was the lumina the only one to get this? Quote
Regal_GS_1989 Posted December 29, 2006 Report Posted December 29, 2006 are you absolutely certaine that its a P and not a T? I ran it through carfax and it shows that its invalid, but that it would be valid with a T instead Quote

GutlessSupreme Posted December 29, 2006 Report Posted December 29, 2006 i want to see this plenum. do a search, it's been posted before. Quote
Regal_GS_1989 Posted December 30, 2006 Report Posted December 30, 2006 Wow, the search function works pretty well now http://www.w-body.com/forum/index.php/topic,34319.0.html Theres a thread with a picture of a variable fuel lumina Quote
White93z34 Posted December 30, 2006 Report Posted December 30, 2006 so what ALL sets a flex fuel 3.1 lumina apart from a standard 3.1 lumina? Quote
